Malayalam ASR datasets

Malayalam is delivered fast, with dense connected speech and few pauses for an annotator to work with. Public speech corpora are far smaller than for Indian languages of comparable speaker numbers, and the pool of qualified annotators is correspondingly small, which means the same people recur across projects. Speaker deduplication and annotator deduplication are both checked, not just the first.

What ASR work in Malayalam requires

Transcription convention, decided first

Whether to write what was said or what should have been said is the single biggest source of disagreement between annotators. For this language the two diverge often enough that the convention has to be explicit.

Speaker count over hours

Recognition models overfit to voices faster than to vocabulary. A dataset that is long but narrow will test well on held-out audio from the same speakers and fail on anyone new.

Noise that matches deployment

If the model will run on phone audio in a city, training on studio recordings creates a mismatch that no amount of additional clean data fixes.

The mistake that costs the most

The most common mistake is specifying hours without specifying speakers, and then discovering at evaluation time that the model only works on the people who were recorded.

The language-specific factor

Malayalam is spoken fast, with dense connected speech, and public speech corpora are far smaller than for Indian languages of comparable size. The pool of qualified annotators is small, so a single project easily reuses the same people: speaker deduplication is mandatory.
